Effect of greenhouse conditions on Zn, Fe and Cu content in tomato fruits

Abstract

Tomato investigations were carried out under greenhouse and field conditions. The aim was to determine the extent to which greenhouse conditions influence the chemical composition of tomato fruits. Plants grown under field conditions were used as the control. Tomato trials were performed during different periods. Greenhouse trials were carried out in the winter and the spring period (January-June), and field trials in the spring and the summer period (May-September). Zinc (Zn), iron (Fe) and copper (Cu) content was established in ripe tomato fruits. Greenhouse conditions were found to effect zinc and iron content in tomato, whereas copper content was unaltered.

Paradajz je proučavan u stakleniku i na otvorenom polju. Proučavanja su obavljena da bi se odredio uticaj staklenika na hemijski sastav plodova paradajza. Otvoreno polje je uzeto kao kontrola. Ogledi sa paradajzom su izvođeni u različito vreme. U stakleniku su izvođeni u toku zime i proleća (januar-juni), a na otvorenom polju su izvođeni u toku proleća i leta (maj-septembar). U zrelim plodovima paradajza određen je sadržaj cinka (Zn), gvožđa (Fe) i bakra (Cu). Staklenik je uticao na sadržaj cinka i gvožđa u paradajzu, dok se sadržaj bakra nije menjao.
